# Before VS 2017 15.8, the member "type" would non-conformingly have an
# alignment of only alignof(max_align_t). VS 2017 15.8 was fixed to handle this
# correctly, but the fix inherently changes layout and breaks binary
# compatibility (*only* for uses of aligned_storage with extended alignments).

<li>For a variable <code>x</code> of any type: <code>unsafe.Alignof(x)</code> is at least 1.
</li>

<li>For a variable <code>x</code> of struct type: <code>unsafe.Alignof(x)</code> is the largest of
   all the values <code>unsafe.Alignof(x.f)</code> for each field <code>f</code> of <code>x</code>, but at least 1.

<li>For a variable <code>x</code> of array type: <code>unsafe.Alignof(x)</code> is the same as
